HMF 241283607488 Swamp Exhaust: Yamaha Grizzly 660

The Swamp & Swamp XL Series set a whole new standard for the horse power, sound, and durability an exhaust adds to a machine. The 304 Stainless Steel, 5" diameter shell gives the exhaust more internal volume producing insane horse power gains. The inlet is TIG welded shut for a completely water tight seal in conjunction with the snorkel kit. Choose the type of sound you need with two different versions; The Swamp Series that controls sound levels to approximately 1-2 dB over stock or The Swamp XL Series with an unrestricted core that will make your machine louder than ever.
